Answer 2

Option (d) will be the correct option

Step-by-step explanation:

We know that 1 horse power is equal to 745.7 watt

We have to convert this J/sec to foot-pound/sec

Other unit of watt is joule/sec

So 1 horse power = 745.7 J/sec

We know that 1 joule = 0.7375 foot-pond

So 745.7 J =
`745.7* 0.7375=550fott-pound`

So 745.7 j/sec = 550 foot-pound/sec = 550 ft-lb

So option (d) is the correct option
